One object of this invention is to adapt the principle of the double pointed pin fastener of the Boden, King and Chapman Patent, .No. 1,604,801, granted October 26, 1926, for use with a snap fastener element. To this end the invention consists in replacing the cap of that patent by a perforated cap, which in connection with'a modified looped head of the pin embodies a'socket member for cooperation with a compl-emental stud member. I c

When used for securing covers'to upholsteredbodies, the stud member Will be attached to the cover'and the socket members will'be stuck in the upholstered portions of the body and thus may be applied to register correctly with the fixed stud members, so thati the stud members may be engaged with the socket members by entering the holes in the socket members and then snapped intospring engagement with the limbs of the looped head. i y

Another object of the invention is to utilizelthemodifie'd form of double-pointed pin in a non-snap fastener, and to this end the invention consists of a double-pointed pin having the aforementioned modified head and a nonperforated cap.

In the accompanying drawings illustrat ing the invention, in the several figures of which like parts are similarly designated, Figure 1 is a front elevation, Fig. 2 a rear elevation, with one limb of'the pin member broken out, and Fig. 3 is a longitudinal seotion illustrating one embodiment of the invention; Fig. 3 also showing one form of stud conventionally. Fig. 4 is a front eleva Y tops 4 where the head is bent over from the 7 tion of the pin detached. Fig. 5 is a rear elevation of. a modified form of cap detached. 6 is alongitudinal section illustrating the invention as applied to a closed or 11011". socket'cap.

The double-pointed pin herein shown has a pair of pointedsubstantially parallel limbs 1, with the bent-over integral head portion. This head portion comprises the diverging side members2,the bend 3, and the humped tops of the limbs 1. The members 2 project-laterally beyond the limbs 1, and the bend 3 crosses the limbs transversely and forms the spring element of a snap fastener socket member which is adapted to engage a complemental head or stud of such fastener.

It will be observed that the bent-over'or humped head is substantially triangular in 0utline,.the sides 2 forming the sides of the triangle and the bend 8 the base of the tria 5 is a cap member having the central open- 1ng'6 for cooperat on with the stud member.

This cap also has the peripheral flange 7 adapted to engage the pin head by embrac- As will appear by reference to Figs. 1,

2 and 3, the portion 3 crosses the opening 6 in the. cap so as'to come into contact with the stud.

In order to ensure the spac ing apart of the members of the pin head, the flange of the cap'may have an intu'rnedportion 9,

which, while limiting the approach of the portions 1.4 of the pin head, yet permit the necessary play of these portions laterally.

This portion 9 also prevents the rotation of the cap on the pin; The limbs of the pin may enter notches 10 in the flange of .the cap to revent'undue movement of said limbs in stic ing the pin into an article. The cap also may be provided with an inverted V-shaped prong 11 rising from the bottom of the flange of the cap and'between the notches 10,

although as indicated in Fig. 5, a cap without'suoh 2. prong may be used.

The prong is fixed and adapted to engage automatically the fabric on which the fastener is used to prevent the accidental escape of the fastener. To disengage the prong from the fabric, a thin tool, such as aknife blade, may be inserted between the fabric.

and the bottom of the cap, to thereby force the llmbs ofthe pin away from the prong andalso force the fabric over the point of the prong. v

The front of; the cap is shown, partieue larly in Fig. 3, as flat and in the preferred construction, this front will be fiat or as nearly flat as possible so as to afford the least possible projection of parts in use and thereavoid annoyance to the users. 1

The upper portion of the hole'in the cap is made with the inturned tongue 12. which is designed to bear againstthe stud head as it engages with the socket spring, to keep the axis of the stud or head substantially normal to the plane ofthe front of the cap.

ithont; such a tongue this normalcy would not he nniintainerl and the snap action would he poor; and moreover, the thin edge of the hole might in eil'eet. hook into the F groove or lcnnrl on the stiiil and interfere with a smooth releasing action.

The head oi? the pin atlorils aniple resilienee in the Foehet nienlhei'. When the steel lit in nreswml on the wire niiileeetion or bend 173 the pin will spring yieltlingg'ly at the point ot eontaet and. also at the two hilnipe about where the long straight pin nienihei's begin. 'lheee humps would a i iproach each othei' and would return to normal position aiitei' the tension eaneetl h the stinl vae released.

In other worth, the cap of the non-socket; pin may he of any oi the con structions herein disclosed, excepting that it not utilized as a socket nieinher and the tongue 12 is not nsecl.
